App1icati0n filed July 25, 1911, Serial No. 640,406. Renewed March 24, 1913..

To all whom it may concern:

' Be it known that I, RAFFAELE FEOLA, a subject of the King of Italy, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Look, of which the following is a full, clear, and exact description.

This invention relates to looks for use with doors and other closures and has reference more particularly to a lock which comprises any suitable key-controllable mechanism including a bolt-actuated member, a

casing, a bolt therein, normally operative means for operatively connecting the bolt and the actuating member, and means whereby the connecting means can be rendered inoperative to adapt the bolt for manual operation independently of the key-controllable mechanism.

The object of the invention is to provide a simple, inexpensive and durable lock which can be used with doors, shutters and other closures, with which any suitable keycontrollable mechanism can be employed,

which cannot be picked without great difliculty, in which the key-controllable mechanism can be rendered inoperative with respect to the bolt, to permit independent manual operation of the bolt, and in which the bolt can be secured against operation by the key-controllable mechanism or otherwise.

The invention consists in the construction and combination of parts to be more fully described hereinafter and particularly set forth in the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference'indicate corresponding parts in all the views, and in which Figure 1 is a perspective view showing an embodiment of my invention applied to a door; Fig. 2 is an enlarged, transverse section showing the bolt and parts of the op-' erating mechanism; Fig. 3 is an enlarged, horizontal section on the line 33 of Fig. at showing the connection between the keycontrollable mechanism and the bolt-actuating mechanism; and Fig. 4 is an enlarged, vertical sect-ion on the line 4-4 of Fig. 2.

Before proceeding to a more detailed explanation of my invention, it should be clearly understood that while I prefer to employ with the same, key-controllable Specification of Letters Patent.

mechanism of the pin tumbler type, any other means adapted for the purpose can be used. The lock is designed particularly for use with doors of apartment houses or other dwellings where there is danger of unauthorized entry on the part of sneak thieves or others, and is intended to prevent the possibility of having the door-lock forced or picked. The lock includes a very strong extension bolt which will securely hold the door closed, and with which are associated a keeper and a guard of proportionate dimensions.

Certain of the details of construction shown for example herewith, form no part of the invention and can be varied in accordance with individual preference and special conditions, without deviating from the essence of the invention as defined in the appended claims.

Referring more particularly to the drawings, I employ a lock casing 10 fashioned from cast metal or any other suitable material, and having an ornamental, removable cover 11 secured thereto by means of screws or rivets 12. The casing is of elongated form and is open at one end. Adjacent to the open end it has a downward extension 13 over which rests a corresponding extension 14 of the cover. Within the casing and slidable over the extension 18 is a bolt 15, which is of suitable length and cross sectional form to insure great strength. The cover 11 has a slot 16 extending longitudinally thereof, through which projects the stem or shank of a manipulating member 17 presenting a knob which can be easily grasped in the hand. The shank of the manipulating member is received in any one of a plurality of'threaded or otherwise suitably formed openings 18 of the body so that the bolt can be moved backward and forward in the direction of its length, by means of the manipulating member or knob. At the lower edge or face the bolt is provided with a plurality of teeth 19 which constitute a rack, for a purpose to appear hereinafter.

The casing it will be understood, is mounted upon the door 20 in any suitable manner, and is arranged to register with a keeper 21 secured by means of screws 22 upon the door frame 23. The keeper has a U-shaped offset or socket 24 into which the bolt can be projected to lock the door. Between the casing and the keeper, at the edge of the lock casing.

. has an offset flange 28, which, when the door is closed-extends over the correspond: lng adjacent edge of the keeper, as 1s clearly shown 1n Figs. 2 and 3. WVhen the bolt is projected, it extends through the sockets 24 and 27 of the guard and the keeper, and the door is thus firmly locked. The guard renders it practically impossible to open the lock-by thrusting an implement through the crack of the dooragainst the bol tand forcing the same rearwardly. The flange 28 assists in insuring that the lock cannot be opened in this manner.

Mounted at the outside ofthe door is a suitable key-controllable mechanism 29, forexample, pin tumbler mechanism, operated by meansof a-properly sh aped key 30; The barrel 31 of the mechanism is located in an opening 32 of the door, and has an extended actuating member 33 which passes through an opening 34 of the door into the extension The actuating member 33 in the present instance consists of an: elongated bar having a longitudinal slot 35.- The extension of the lock casing has an openingregistering with the opening 34, and atthis openingis formed into a-bearing 36. I employ a gear pinion 37 normally in mesh with the rack ofthe bolt and having a hub 38 journaled in the bearing 36. At the opposite side the pinion has a slotted orsplit collar 39.-

Thepinion has a bore oropening 40 inwhich is mounted a cylindrical releasing member 41 having a central, longitudinal opening 42 in which is received the actuatin-g member 33. The transverse pin 43 is locatedin the slot 35 of the actuating member and limits the movement of-the releasing member 41 relative to the actuating member; The releasing member 41, intermediate its ends has lateral wings or proj ections 44 normally received 'in the openingsof the slotted collar 39, so that the pinion is constrained to turn with the releasing member and with the actuating member. A spring 45 engages the projections44 and under a rounded, offset 46 of the cover extension 14, normally pressing the releasing member into operative engagement with the collar of the pinion. The part 46 of the cover has an opening 47 through which the end of the releasing member extends. A manipulating-button or head 48 secured by means of a screw 49, or in any other suitablemanner to the releasing member, permits the latter to be drawn out manually against the tension ofthe spring, so thatit canbe released from the pin-ion, and-servesto disconnect the latter andthe key-controllable mechanism,

the lat-ter toward the collar:39. The keepen has the end within the casing extension suit? ably formed toengage under the projections 44 of the releasing member when the same is moved into an inoperative position, that is,

when it is pulled out, againstzthe tension of the spring 45.

In the normal condition of the lock, the actuating member 32 can be turned by means of the key 30 and the bolt moved backward and forward accordingly. VV-hen it;is de sired to renderthe key-controllable mecha-: nism inoperative relative to the bolt, the keeper 53 is moved aside, againststhe tension of the spring55, by means ofits projecting end, and the releasing member is drawnout against the tension o'f'its spring; thereupon the keeper 53 is allowedtospringunder the wings or projections 44 of the releasing member, and thus serves to hold this-in 1 an inoperative position against the tension of the spring 45. The pinion can then be turned as the bolt is m-ovedbackwardiand forward by means of the manipulating member 17 without altecting the key-controllable mechanism through the actuating member 33-. To connect the latter andthe pinion again itism-erely necessary topress the end53- of the keeper to allow the releasing member to be sprung backinto its normal position. Should it be desired to permit the bolt to be securedfr-om the inside'so that it cannot be actuated manually or by the key-controllable mechanism, I employa holding device 57 consisting of a double hook-shaped member pivotally mounted upon the cover 11 ofthe casing, and adapted to have one orthe other of its hooks-engage the manipulating member 17, which is' th en:

located at one end of the slot 16, and is thus held against movement 1 in either direction,

I employ a plurality of openings-18 m that the manipulating 'member can be ad justed relatively to the boltto determine the part of the bolt length to be projected when the-lockis closed. In this way the device can be adapted for doors or door framesof different dimensions and styles.

Having thus described my invention, I claim as new, and desire to secure by Letters Patent:

1. A lock comprising key-controllable mechanism, a slidable bolthaving a rack, a-

pinion in'mesh with'said rack, and a sepmember movable relative to said arate releasing member between said pinion and said key-controllable mechanism and movable relatively thereto, though operatively connected therewith.

2.
